초록

A silicon carbide (SiC) ceramic filter is an effective component for hot flue gas cleaning because of its high collection efficiency, high thermal shock resistance, and excellent mechanical strength. The effect of molding pressure in the production of SiC granular ceramic filters, on the mechanical strength and filtration performance, was investigated in this work. It was found that the ceramic filters produced at molding pressures less than 20 MPa have low mechanical strength and that this result was caused by weak physical interaction among the ceramic powders due to defects and cracks. On the other hand, the filter quality factor(qF), which represents filtration performance of filter media, decreased with increasing the molding pressure due to the drastic increase in pressure drop. Ceramic filter performance factor(qFM), which is the manipulation of maximum mechanical strength and qF, was introduced to consider both mechanical strength and filtration performance in this study. As a result, molding pressure of 30 MPa was desirable to produce a SiC granular ceramic filter based on qFM.
